이지혜(Lee Ji Hye) 학습자중심교과교육학회 2015 학습자중심교과교육연구 Vol.15 No.8

본 연구는 예비교사와 현직교사의 도덕적 행동에 관심을 갖고, 이에 영향을 미치는 자아관련 변인들(자기성찰, 자기통제력, 도덕적 정체성) 간의 관계를 Blasi(1980)의 자 아모형(self-model)에 논리적 근거를 두고 이지혜(2015)가 제시한 구조방정식모형이 예비교사와 현직교사 간에 어떠한 차이가 있는지를 밝히는데 목적을 두었다. 이를 위 하여 본 연구는 충북에 소재한 2개 대학교 예비교사를 대상으로 303개의 자료를, 그 리고 충북에 소재한 중학교 4개교와 고등학교 2개교에 재직 중인 현직교사를 대상으 로 333개의 자료를 Amos 20.0으로 최종 분석하였다. 분석결과는 다음과 같다. 첫째, 이지혜(2015)의 연구에서 제시한 모형을 예비교사와 현직교사 전체를 대상으 로 적용해본 결과, 구조방정식모형의 적합도는 χ2=625.173(df=128, ρ=.000), RMSEA=.078, GFI=.908, TLI=.942, CFI=.948, NFI=.933으로 모든 기준을 충족하였다. 따라서 예비교사를 대상으로 검증한 이지혜(2015)의 구조방정식모형은 예비교사뿐만 아니라 현직교사를 포함하여 적용하는 것도 가능하다는 것을 알 수 있다. 둘째, 이상 의 구조방정식모형을 예비교사와 현직교사 모형으로 분리하여 분석한 결과, 두 모형 모두 적합도 지수 기준에 충족하는 것으로 나타났다. 그러나 예비교사와 현직교사 모 형에는 통계적으로 유의한 차이를 보였다. 구체적으로 모든 경로에서 유의한 영향력 이 있는 것으로 나타난 예비교사와는 달리 현직교사의 경우 도덕적 정체성이 도덕적 행동에는 유의한 영향력이 없는 것으로 나타났다. 따라서 도덕적 행동을 높이기 위해 서는 예비교사와 현직교사에게 차별적인 조력이 필요할 것이다. The aim of this study was to investigate the moral behavior of pre-service teachers and in-service teachers. Using the self-model of Blasi(1980) as a theoretical basis, we analyzed the relationships between self-related variables(self-reflection, self-control, moral identity) that influence moral behavior, and we aimed to reveal the differences between pre-service teachers and in-service teachers using the structural equation model suggesting by Ji-Hye Lee(2015). To this end, we performed a final analysis using Amos 20.0 on data from 303 pre-service teachers in 2 universities situated in Chungbuk, and data from 333 in-service teachers at 4 middle schools and 2 high schools in the same area. The results were as follows. First, when we applied the model of Ji-Hye Lee(2015) to pre-service teachers and in-service teachers, the fit of the structural equation model fulfilled all criteria, with χ 2=625.173 (df=128, ρ=.000), RMSEA=.078, GFI=.908, TLI=.942, CFI=.948, and NFI=.933. We showed that the structural equation model of Ji-Hye Lee (2015), which was originally validated on pre-service teachers, could be applied to in-service teachers as well as pre-service teachers. Second, when we analyzed the above model separately for pre-service teachers and in-service teachers, both models were found to fulfill criteria for fit indices. However, there was a statistically significant difference between the pre-service teacher model and the in-service teacher model. In other words, unlike the pre-service teacher model, in which there is a significant effect in all pathways, for the in-service teacher model, there was no statistical effect of moral identity on moral behavior. Accordingly, in order to increase moral behavior, different assistance will be required for pre-service and in-service teachers.

A bulk-type Ta material is fabricated using the kinetic spray process and its microstructure and physical properties are investigated. Ta powder with an angular size in the range $9-37{\mu}m$ (purity 99.95%) is sprayed on a Cu plate to form a coating layer. As a result, ~7 mm-sized bulk-type high-density material capable of being used as a sputter material is fabricated. In order to assess the physical properties of the thick coating layer at different locations, the coating material is observed at three different locations (surface, center, and interface). Furthermore, a vacuum heat treatment is applied to the coating material to reduce the variation of physical properties at different locations of the coating material and improve the density. OM, Vickers hardness test, SEM, XRD, and EBSD are implemented for analyzing the microstructure and physical properties. The fabricated Ta coating material produces porosity of 0.11~0.12%, hardness of 311~327 Hv, and minor variations at different locations. In addition, a decrease in the porosity and hardness is observed at different locations upon heat treatment.

The tandem welding process is one of the most efficient welding processes widely used in material joining technique such as manufacturing of strong and durable structures. It facilitates high rate of joint filling with little increase in the overall rate of heat input due to the simultaneous deposition from two electrode wires. The two electrodes in tandem welding process helps in high-efficiency and high productive of welding process. In this study a automated tandem welding system is developed to determine the correlation between cathode and anode and compared with current ratio of the two electrode torch. Three different inter-electrode distances were chosen, 25mm, 35mm and 45mm to perform the experiment with three different current ratio. From the experiment results, the current ratio between two torch has a large impact on width, height and depth of penetration. In addition, a stable bead geometry is obtained when inter-electrode distance is 35mm.

The water soluble quantum dots (QDs) are synthesized by the phase transfer and silica coating reaction. The photoluminescence intensity of silica-coated QDs are mainly affected by the amount of phase transfer agent, SDS (sodium dodecyl sulfate), and the maximum value is obtained at the cmc (critical micell concentration) concentration of SDS in the phase transfer reaction. Based on fluorescence spectra and field emission transmission electron microscope (FETEM), the energy transfer rate by forster resonance energy transfer (FRET) is increasing with the thickness of the silica shell coated on CdSe/ZnS QDs.

The effect of heat treatment environment on the microstructure and properties of tantalum coating layer manufactured by kinetic spraying was examined. Heat treatments are conducted for one hour at $800^{\circ}C$, $900^{\circ}C$, and $1000^{\circ}C$ in two different environments of vacuum and Ar gas. Evaluation of microstructure and physical properties are conducted. High density ${\alpha}$-tantalum single phase coating layer with a porosity of 0.04% and hardness of 550 Hv can be obtained. As heat treatment temperature increases, porosity identically decreases regardless of heat treatment environment (vacuum and Ar gas). Hardness of heat treated coating layer especially in Ar gas environment deceases from 550 Hv to 490 Hv with increasing heat treatment temperature. That in vacuum environment deceases from 550 Hv to 530 Hv. The boundary between particles became vague as heat treatment temperature increases. Oxygen distribution of tantalum coating layer is minute after heat treatment in vacuum environment than Ar gas environment.

Niobium is one of the most important and rarest metals, and is used in the electronic and energy industries. However, it's extremely high melting point and oxygen affinity limits the manufacture of Nb coating materials. Here, a Nb coating material is manufactured using a kinetic spray process followed by hot isotactic pressing to improve its properties. OM (optical microscope), XRD (X-ray diffraction), SEM (scanning electron microscopy), and Vickers hardness and EPMA (electron probe micro analyzer) tests are employed to investigate the macroscopic properties of the manufactured Nb materials. The powder used to manufacture the material has angular-shaped particles with an average particle size of $23.8{\mu}m$. The porosity and hardness of the manufactured Nb material are 0.18% and 221 Hv, respectively. Additional HIP is applied to the manufactured Nb material for 4 h under an Ar atmosphere after which the porosity decreases to 0.08% and the hardness increases to 253 Hv. Phase analysis after the HIP shows the presence of only pure Nb. The study also discusses the possibility of using the manufactured Nb material as a sputtering target.
